7 2 claims. (o1. isl-als) rIthis invention' relates to smokers pipes, and particularly to improved means for Ydisposing of the moisture developed by, and incidentto, the smoking of a pipe, without permitting the moisture resulting from either the distillationof the tobacco or the salivary discharge of the smoker to enter or return to the mouth from the pipe. As is wellV known, such moisture becomes loaded with poisons, condensed from the burning tobacco, and these poisons are definitely injurious, as well as unpleasant, if swallowed. Many attempts have been made, involving the use of lters, traps, and other expedients, -to dispose of the moisture, pre-condense the tars and other foreign substances, or otherwise guard against poisoning the smoker. Y i

Those pipes previously known which have utilized moisture traps and fltershave ordinarily been designed to catch and hold thesaliva, to-

gether with any moisture distilled from the burnof polluted saliva therefrom, is apt to enter the mouth in greater quantities than is possible with an ordinary pipe without a trap. The present invention accordingly aims to provide such a pipe construction having separate traps for collecting and holding the saliva and the liquid condensed from the tobacco, and which keeps the saliva from; mingling with and becoming polluted by the poisonous condensation productions, so that even should the user neglect to empty the saliva trap, it would be impossible for him to draw polluted saliva into his mouth, while the nature and 1ocation of the condensation trap and the viscous character of the condensation products make it impossible for these to run or be drawn into the mouth at any time. f

It is common practice in the construction of pipes to allow the saliva to mingle with the smoke throughout the length of the stem. 'I'he protection aiorded by such a pipe, even though equipped with a trap, is imperfect because of the tendency of poisons to condense in the saliva as it runs through the stem. Even though only a small quantity of the polluted saliva is drawn back into the mouth with the smoke at the next inhalation, the cumulative effect is extremely injurious. Normally the quantity of saliva to be disposed of greatly exceeds the quantity of liquid distilled from the tobacco. With the foregoing in mind, another important object of the present invention is to provide an improved pipe construction so designed that the smoke cannot -rningle withthe saliva to any material extent, and which accordingly prevents condensation of appreciable amounts of poisonous material in the saliva. The invention contemplates, further,l the complete separation of the salivary discharge fromr the smoke throughout virtually the full length ofthe stern commencing at `a point close tothe mouth of the smoker. Y v` AStill another object is to providev such a pipe having separate traps for condensate and' for saiivary` discharge, incorporating common sealing means for the separate trapsA above referred to, whereby, by removal of a single sealing element, both traps may be cleaned at once. y

Other objects and advantages will be apparent from the following description, wherein reference is made to the accompanying drawing illustrating apreferred embodiment of my invention and wherein similar reference numerals designate similar parts throughout the several views.

vlin the drawing: l A

YFigure 1 is a substantially central longitudinal section, upon an enlarged scale, showing a pipe constructed in accordance with the present `invention.

Figure 2 is a sectional view taken in the same plane as Figure l with the bowl and part of the steml Vportion broken away, and showing the mouthpiece and stem portions separated from one another.

Figure 3 is a sectional view taken substantially on the line 3-3 of Figure 1 and looking in the direction of the arrows.

Referring now to the drawing, reference character I8 designates the bowl portion of my improved pipe. The bowl, together with the stem I2, may be formed of briar, although the material used is subject to variation. A removable mouth-piece I5 is attached to the end of the stem. Two longitudinal passages `lil-0 are formed in the stem, passage I8 being smaller than and arranged above passage`2, and communicating with a bore I9 entering the bottom of the bowl in the usual manner. A portion of passage 20 nearest bowl I0 is enlarged to provide a reservoir of substantial size for saliva, and a continuation 22 of passage 20 extends through the mouthpiece I5 and is in sealed engagement with the passage 2 when the mouthpiece is attached, as shown in Figure l. The central tubular portion 23 of the mouthpiece defining the channel 22 is connected to the hollow interior of the mouthpiece only by a small passage 25, located in the top of the channel and close to the end of the mouthpiece. The hollow interior IE of the mouthpiece communicates with the smoke passage I8 when the mouthpiece is attached to the stem. An angular bore 26 beneath the bowl connects passage I3 at its opposite end with the enlarged passage 2l forming the saliva reservoir. Passage 2l is open at its end beneath the bowl, and tapped, the threads extending inwardly beyond the open end of the passage 26. A plug 30 isthreaded thereinto. The plug is centrally cut away, as indicated at 3|, to provide anenlarged space for the reception of condensation products, which drop thereinto through the passage 26. The plug at the same time seals offV the saliva trap 2|, as shown in Figure 1. ,The

head of the plug is provided with a squared end 33 adapted to receive a wrench (unshown) by means of which it may be conveniently removed for cleaning.

I am aware that the invention may be em-y bodied in other specific forms without departing from the spirit or essential attributes thereof,

and- I Vtherefore desire they present embodiment to be lconsidered in all respects as illustrative and not restrictive; reference being had to the appended claimslrather than tothe foregoing description to indicate the scope of the invention.

I claim:

l. A smoking pipe construction comprising in combination with a bowl, a stem attached to the Cil passage providing communication between said saliva compartment and smoke passage at a point near said bowl, and common plug means for sealing said saliva compartment on opposite sides of said second connecting passage, said plug means having a recess forming a well for liquid condensed in the bowl and/or smoke passage as Well as for any liquid material melted or otherwise resulting by reason of the burning of tobacco in the b oWl.. y

' 2.Y A smoking pipe construction comprising in combination with a bowl and stem, a mouthpiece removably attached to the stem having a central passage throughout its entire length, a surrounding chamber extending throughout the major portion of the mouthpiece, and an opening connecting said chamber and central passage adjacent the rear extremity of the mouthpiece, the stem having a pair of separated passages extending throughout the length of the stem, the lower lof such'passages communicating with the central passage of the mouthpiece to form a saliva compartment and the upper of said stem passages communicating with the upper portions of the surrounding chamber in the mouthpiece, an inclined passage at the forward extremity of the pipe stem connecting the forward extremities of the upper and 'lower stem compartments, a passage from thebowl extending into such inclined passage', Ymeans for sealingrthe forward extremity of the saliva `compartment of the stem rearwardly of said inclined passage, and additional sealing means spaced from the rst mentioned sealing means and located at the extreme forward extremity of the saliva compartment, whereby a well for liquid condensed in the bowl and/or smoke passage as well as for any material melted or otherwise resulting by reason of burning in the bowl is formed in the lower extremity of said inclined passage and between said sealing means.
